There are a couple of things to be careful about. First, it's packages rather than a volume. Secondly, just because the beer was dispatched from a port in Belgium or Holland, it doesn't necessarily mean that the beer was brewed there. Much likely came from somewhere else, most likely Germany.
Though the beer shipped from Copenhagen probably did come from Denmark. And I think it's safe to assume anything coming from New York had been brewed in the USA. I'm shocked to see that any beer at all was imported from the US. The stuff coming from Copenhagen was probably mostly Carlsberg and Tuborg.
The beer itself was probably almost all Lager. That was about all that was imported into the UK. Top-fermenting styles were provided by domestic breweries.
Note that more than half of the imports came in via London. Not really surprising: London waws a massive port and much closer to the Continent than Liverpool, Dublin or Glasgow. I'd guess that the same was also true for exports. Though maybe not to quite the same extent.

Here are the numbers in bulk barrels:

As 1 package seems to equate to about a third of a barrel, here's are the bulk barrels for each point of origin:
It's not a huge amount of beer.
